Why PU is Ideal for CNC Machining

What
Polyurethane (PU) is a polymer material available in a wide range of hardness levels, from soft elastomers to rigid plastics. It offers outstanding abrasion resistance, flexibility, and load-bearing capacity, making it suitable for dynamic parts exposed to wear, shock, and vibration.
Advantages
High abrasion and wear resistance
Excellent impact strength and toughness
Flexible hardness range (soft to rigid)
Good resistance to oils, greases, and solvents
Shock absorption and vibration dampening
 
Applications
Seals, gaskets, and O-rings
Wheels, rollers, and bushings
Automotive suspension components
Industrial machine parts exposed to wear
Protective covers and cushioning parts
